IMPROVEMENT IN STOVES.

Specification forming part of Letters Patent No. 42,537, dated May 24,1864.

To all whom it may concern:

Be it known that I, RICHARD CHEsTER, ot' the city of Chicago, in thecounty of Cook and State of Illinois, have invented a new and usefulImprovement in Goal-Stoves; and I do hereby declare that the followingis a full, clear, and exact description of the stme, reference being hadto the accompanying drawings and letters ot reference marked thereon,which form a part of this specification, in which Figure 1 represents avertical sectional view at the red line ac in Fig. 2, and Fig. 2, a hrizontal sectional view at the red line in Fig. 1.

The nature of my invention consists in so constructing a coal-stove thatthe draft may be made either direct from the top of the fire-pot intothe escape-pipe leading to the chimney or applied near the base of thefirepot, carrying the heat to a chamber at the top of the stove andthence through pipes to its base, and there so distributed that none ofit is lost by passing out of the chimney.

The same letters of reference are used to represent corresponding andsimilar parts in the different figures.

To enable those skilled in the art to manufacture and use my invention,I will proceed to describe it with particularity.

I construct that part of the tire-pot which contains the fire larger indiameter than the upper part of it. These two parts of the fire pot aremarked in Fig. 1 A and C, respectively. The base of C is indicated bythe circle h, and the top of A by the circle 6, the square shoulder orplate D extending from the one to the other. Through the said plate Dare the pipeholes a and b, over which are the pipes marked with the sameletters. In the base A of the fire-pot there is a partition, E, whichkeeps the fire in the front part of it under the pipes a. The chamber Brests on the pipes a and b, and has a pipe h leading out of it directlyinto the escapepipe p. z is a damper, which, when drawn out, opens boththe top of the fire-pot C and the pipe h. F is a sheet-iron case,forming the outside of the stove, and'may be either open or closed atthe top. a and e are pipes for conducting the heat around the base ofthe stove and f is open work between said pipes. r and s are solidpartitions in the pipes c and e, and d is a pipe connecting the two saidpipes.

When the fire is kindled, the damperz' is drawn forward, which allowsthe smoke to escape into the chamber B and directly into the escape-pipep, but, when the fire is well burning, by pushing back the damper thetop ofthe fire-pot C is closed and also the pipe h, when the heat canescape from fire-pot only through the pipes marked at. These pipes leadinto the chamber B but the pipe h being closed the heat is forced downthe back pipes, I), through the passage 00 into the circular pipe at thebase of the stove, (marked 6.) By means of the partition in the pipe 0,which is represented by the dotted line r, the heat is caused to passquite round in c, as indicated by the arrows, to the connecting-pipe d,and through it into the circular pipe 0. There is also asimilarpartition in this pipe, (shown at 8,) which causes the heat to passround in e, as indicated by the arrows, to the escape-pipe p. The numberof these circular pipes could be increased, but two is sufficient toshow the principle.

There are two small doors opening into each of the circular pipes tofacilitate cleanin g them.

Having thus fully described the construction and operation of myimproved coalstove, what I claim as my invention, and desire to secureby Letters Patent, is-

1. The arrangement of the partition E in the firepot A, when constructedand operating substantially as and for the purposes set forth.

2. The combination and arrangement of the partit on E, the frontpipes,a, the chamber B, the return-pipes b, the passage av, and the circularpipes c and 6, when con' structed and operating substantially as setforth.

3. The combination and arrangement of the damper i, the chamber B, thepipe h, the fire pot C, and the partition E, when all arranged andoperating substantially as herein delineated and described.
